Abstract: The systems and methods described herein include monitoring systems and methods that monitor speeds of a motor of a vehicle represented as a pulse signal indicative of a rotational position of the motor. The systems and methods include receive a pulse signal from a speed sensor coupled to a traction motor. The pulse signal is indicative of a rotational position of the traction motor. The systems and methods include analyze the pulse signal to identify per-revolution signal reoccurrences that meet designated criteria, and determine a defect based on the per-revolution signal reoccurrences that are identified. The defect is one or more of a wheel defect, a bearing defect, or a gear defect.

Abstract: Diagnosing equipment coupled to a generator. A condition of the equipment is diagnosed based on information provided by signals from a generator operationally connected to the equipment or other signals associated with an engine. Different types of degradation are distinguished based on discerning characteristics within the information. Thus, a degraded equipment component can be identified in a manner that reduces service induced delay.

Abstract: A system for use with a vehicle includes at least one nozzle and an fluid reservoir capable of holding a volume of pressurized gas or other fluid. The air reservoir is in fluid communication with the at least one nozzle and the at least one nozzle is selectively operable to direct the pressurized gas or other fluid at a surface of an optical inspection sensor assembly to remove contaminants from the sensor assembly.
